Data corruption is the damage of information due to various software or hardware fails. When a file gets corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as failures are very likely to happen on bigger hard disk drives where vast volumes of info are stored. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and will be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers today often cannot find corrupted files in real time or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your websites in a shared web hosting account from our company, you will not need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All of the file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file will not be corrupted. This may happen throughout the writing process on any drive and afterwards a damaged copy can be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives right away and when a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. In this way, your info will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any silent data corruption issues whatsoever in case you purchase one of our semi-dedicated hosting solutions as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all of your files are undamaged all the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on a number of drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system out there which uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
